This thesis utilizes pulse shaping in characterization of high efficient wavelength tunable terahertz radiation. The influence of multi-pulses generation under different tunable chirp and time delay are characterized by Cross-FROG measurement. A strong enhancement of total power is observed from spectrum. Furthermore, the total power of terahertz radiation is reducing in same multi-pulses spacing experiment as chirp is increasing and negative chirp have higher THz total power than positive chirp.
Meanwhile, we also theoretically and experimentally study the possibility of an alternative approach of enhancing the THz power. This enhancement is attributing to constructive interference between two independently generated THz pulses. This also reveals the nature of quantum coherence and potential of high power THz radiation.
